Binance market data with python

Small project part of an interview process.

Requirements

• Python 3.6 or newer
• ccxt
• asyncio
• either python-binance or binance-connector (they can't coexist in the same enviroment)
• Internet Connection

How to run

• Run this on the repo directory:

pip install -r requirements.txt

• the ws.py & ws_binance.py implementations have incompatible libraries. To avoid this you should either run:

pip uninstall python-binance; pip install binance-connector
python3 ws_binance.py

or

pip uninstall binance-connector; pip install python-binance
python3 ws.py

Implementations

reduction.py

the simpler & most straight foward implementation

ws.py

Asyncronic implementation using BinanceSocketManager to connect to binance streams. It only refresh the displayed data when theres a change in a coin's price.

ws_binance.py

Stright foward implementation using Binance's own connector module.

Useful documentation

• For the main websocket implementation ws.py:

  • python-binance module documentation
  • Binance API docs

• For ws_binance.py:

  I started using the Binance documentation for websockets but i stumbled uopen a library that works as a connector to the Binance Public API:

  • binance-connector module documentation
    • special mention to: examples/websocket/spot/symbol_ticker.py

• For ccxtpro I followed this:

  • Manual (https://github.com/ccxt/ccxt/wiki/ccxt.pro.manual#)
  • Watch ticker python example (https://github.com/ccxt/ccxt/blob/b9f5441a44e740579c9274f84487b6ba7da8e107/examples/ccxt.pro/py/binance-futures-watch-order-book.py)
